Here is the solution I choose.  It also addresses my larger problem, that I have line breaks in paragraphs when I want continuous text.
That is, I want to turn the following:
<===== START EXAMPLE =====>
Some text followed by four paragraph marks that should only be two.
   
   
   
A paragraph
with paragraph marks
that should be continuous.
<===== END EXAMPLE =====>
Into this:
<===== START EXAMPLE =====>
Some text followed by three paragraph marks that should only be two.
A paragraph with paragraph breaks that should be continuous.
<===== END EXAMPLE =====>
Steps to the solution, using regular find and replace:
- 
Replace all “$” with “paragraph1”. 
- 
Replace all “paragraph1paragraph1paragraph1paragraph1” with “paragraph4”. 
- 
Replace all “paragraph1paragraph1paragraph1” with “paragraph3”. 
- 
Replace all “paragraph1paragraph1” with “paragraph2”. 
- 
Replace all “paragraph1” with " " (i.e. a space). 
- 
Replace all “paragraph4” with “\n\n”. 
- 
Replace all “paragraph3” with “\n\n”. 
- 
Replace all “paragraph2” with “\n\n”. 
This is recordable by macro using regular find and replace.
Always a way!
